Answer:
Let the measures of angles of the given quadrilateral be (2 ):, (3 ):,(5 ): and (8 ):.We
know that the sum of the angles of the a quadrilateral is 360: .
∴ 2 +3 +5 +8 = 360
⇨ 18 = 360
Class: 8
No. Of Question: 10
⇨ = 20
So, the measures of angles of the given quadrilateral are
(2×20):, (3×20): , (5x—20): and (8×20):
i.e .,40: , 60: , 100: and 160:
